WRENCH.

SPECIFICATION forming part of Letters Patent No. 462,421, dated November 3, 1891.

Application filed April 21, 1891.

To all whom it may concern.-

Be it known that I, SEBERN JONES IVEVER, a citizen of the United States, residing at Irvin gton, in the county of IVashington and State of Illinois, have invented a new and useful \Vrench, of which the following is a specification.

This invention relates to improvements in combined pipe tongs and wrenches; and the objects in view are to provide a cheap, simple, readily-adjustable pipe tongs or wrench that maybe easily applied to such objects as pipes, rods, bolts, nuts, &c., and is adapted to securely engage therewith.

Other objects and advantages of the invention will appear in the following description,

and the novel features thereof will be particularly pointed out in the claims.

Referring to the drawings, Figure l is a perspective of a combined pipe tongs and wrench constructed in accordance with my invention. Fig. 2 is a vertical longitudinal sectional view. Fig. is a detail in perspective of the locking-bar.

Like numerals of reference indicate like parts in all the figures of the drawings.

In practice I employ two opposite members, (designated as l and 2,) which members are simply levers having their'in'ner ends curved and recessed to overlap each other and pivotally connected, as at 3, so that the members may swing apart at their free ends. Between their ends each member is given an angular bend or recess 4, thus providing a pair of converging faces 5. Opposite these converging faces 5 the members are provided with inwardly-disposed inclined teeth 6, and beyond said portions the members are slightly deflected or diverged to form a pair of gripping-jaws 7. The inner face of one of the jaws is plain, while that of the opposite jaw is toothed, as at 8. A spring 9 is secured to one of the members, is inwardly bent, and has its curved extremity 1O seated for movement in a groove 11 of the opposite member, said spring having a tendency to spread the two members.

12 designates a sliding bar, which is provided near its extremities with a pair of 0ppositely-inclined openings 14, forming at their outer upper edges angles adapted to engage Serial No. 389,824:- (No model.)

the teeth 6 of the converged portions of the members, said members being spring-pressed into such engagement, so that the bar acts to lock the same.

In operation, the bar being at the lower ends of the jaws, in order to grip an object it is simply necessary to introduce the jaws of the wrench over the pipe, rod, or other obj ect and compress the two members together. By reason of the inner inclined faces of the inclined portions of the members the looking sliding bar is forced inwardly and is continued in its movement until the members are released, when the spring serves to suddenly spread the members, interlocking the teeth 6 with the locking-bar, which latter holds the members in position. To loosen the members or distend the same, they are compressed until their teeth release the locking-bar, when with the other hand the operator may slide the locking-bar toward the outer end of the wrench, as will be readily understood.

From the above construction it will be apparent that I provide a device capable of operatin g upon rods, bolts, pipes, nuts, and other objects, that may be readily adjusted, and that is strong and powerful and free from screws 7 or other mechanical devices subject to great wear.

Ilaving described my invention, what I claim is l. The combination, with the opposite members pivoted together at their inner ends and between said ends provided with opposite converging portions and terminating beyond the same in jaws, said converging portions having their outer surfaces provided with teeth, of a spring interposed between and adapted to spread the members, and a bar loosely embracing the inclined portions of the members and engaged by their teeth, substantially as specified.

2. The combination, with the two members pivoted at their inner ends and between their ends provided with oppositely-inclined converged portions, the outer surfaces of which are provided with inwardly-disposed teeth and beyond said portions terminating in jaws, of a spring projecting from one of the members and having its free end curved and adapted to ride in a groove formed in the inner surface of the opposite member and adapted tospread said members, and a locking-bar provided near its ends with converged openings, each receiving a member, the outer upper angles of the openings being engaged by the teeth of the converging portions, substantiaily as specified.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in IO M presence of two Witnesses.

SEBERN JONES VVEVER.
